Quality Control

Our N,N'-Bis(4-Aminobutyl)-1,2-Ethanediamine is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay by titration or HPLC and identification by FTIR, to ensure it meets high-purity standards suitable for industrial and research applications. A Certificate of Analysis (COA) documenting purity, identity, and other critical parameters is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture and carbon dioxide, which can affect product quality.
